That's the neat part, you don't.

The top results have been useless spam for a decade or more at this point, and the only difference is Google sit there hoovering up the money instead. The money is in the way of search. Any popular search engine will end up the same way.

It's a shite situation, but until somebody makes a non-profit search engine and filters out spammy results, we'll continue to Google, scroll down two pages for a reddit link, and carry on.
